Even the characters in animated sci-fi sitcoms can afford to learn a lesson about the true meaning of Christmas, and in this holiday special, it looks like it's going to be a glum Yuletide for George Jetson (voice of George O'Hanlon) when his boss, Mr. Spacely, (voice of Mel Blanc) decides to make him work on an important project on Christmas day. While the Jetson family wonders what's become of George, Spacely is visited by the ghost of his former business partner, Jacob Marsely (also voiced by Mel Blanc), who tries to teach Spacely a lesson about the importance of giving. The Jetson's Christmas Carol also features the rest of the voice cast from the popular animated series of the 1960s, including Penny Singleton as Jane Jetson, Janet Waldo as Judy, Daws Butler as Elroy, and Don Messick as Astro.
